C'mon Brady, a boy from the South that hasn't heard the term "kick butt" used as an adjective? Pulleeeeezzzzzz.
To be able to kick someone's butt is an accomplishment deserving of bragging rights, because that's a great, high-minded way to solve one's differences with your fellow man. Once you have kicked someone's butt, there is no longer any dispute about your superiority over that individual. Therefore, his pond is undisputedly of superior quality. I'll translate that to proper modern American English for you:
His pond is da bomb, tight, or phat. Dale is mac daddy or a big dog, a real player. Filter house rules. Landscape is kickin'. His place is the shizzle foe-zizzle. Got it?
